Packaging box foil stamping process

Abstract

The invention relates to the technical field of packaging box processing, in particular to a packaging box foil stamping process. The packaging box foil stamping process comprises the following stepsthat a pattern to be subjected to hot stamping is scanned by using a scanner, data are stored into a computer, then three-dimensional carving is carried out under the control of the computer and software to form a hot stamping gravure with a three-dimensional pattern and a bottom die relief printing plate matched with the hot stamping gravure; the hot stamping gravure is installed on a stamping machine head of a hot stamping machine; after surface dust removal is conducted on a hot stamping material, the bottom die relief printing plate is positioned on the hot stamping material, and preheating treatment is conducted; the preheated surface of the bottom die relief printing plate is subjected to dust removal again; and the preheated bottom die relief printing plate and the hot stamping material are placed on a stamping platform of the hot stamping machine together, and then under the action of the stamping machine head, the hot stamping gravure is driven to be rapidly pressed down at acertain pressure and temperature. And therefore, the temperature difference between the bottom die relief printing plate and the hot stamping gravure is reduced, the machining difficulty of the bottomdie relief printing plate is effectively reduced, meanwhile, the occurrence rate of the problem that the matching effect is poor due to the temperature difference is effectively reduced, and the foilstamping effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of packaging box processing, in particular to a hot stamping process for packaging boxes. Background technique [0002] Hot stamping is to use the template installed on the hot stamping machine to press the printed product and the hot stamping plate in a short time with the help of moving pressure and temperature, and transfer the metal foil or color pigment foil according to the graphic requirements on the hot stamping template To the processing technology of the surface of the hot material. Since hot stamping is mainly gold and silver, it is called hot stamping. [0003] The hot stamping process is divided into hot stamping technology and cold stamping technology, among which hot stamping technology is related to hot stamping temperature, speed and pressure. At present, in the process of three-dimensional hot stamping, the hot stamping plate will expand due to the increase of temperature, while the tempe...
